我使用API来获取连接信息，但是我无法从该API获取数据，因为我不知道如何使用HTTP输入用户名和密码来获取连接以访问此数据。

主要

String url = "http://flightxml.flightaware.com/json/FlightXML2/";
    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    StrictMode.ThreadPolicy policy = new StrictMode.
    ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy); 

    TextView txt1 = (TextView)findViewById(R.id.textView1);

    String result  = HttpGet(url);
    txt1.setText(result);
                   }
    // Connect Http Get //
    public String HttpGet(String url) {
    StringBuilder builder = new StringBuilder();
    HttpClient client = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet(url);

    try {
    HttpResponse response = client.execute(httpGet);
    StatusLine statusLine = response.getStatusLine();
    int statusCode = statusLine.getStatusCode();
    if (statusCode == 200) { // Status OK
    HttpEntity entity = response.getEntity();
    InputStream content = entity.getContent();
    BufferedReader reader = new BufferedReader(new InputStreamReader(content));
    String line;
    while ((line = reader.readLine()) != null) {
    builder.append(line);}
    } else {
    Log.e("Log", "Failed to download result..");
    }
    } catch (ClientProtocolException e) {
    e.printStackTrace();
    } catch (IOException e) {
    e.printStackTrace();
    }
    return builder.toString(); }}

在浏览器中，我可以输入用户名和密码，但是在Android App中，我不知道如何输入。这张照片一样。

假设您的目标API需要基本身份验证，则需要将凭据添加到请求中，如下所示：

String user = "username";
String pwd = "password";
httpGet.addHeader("Authorization", "Basic " + Base64.encodeToString((user + ":" + pwd).getBytes(), Base64.NO_WRAP));
